Agents manage clients, prospects, suppliers, and contacts, maintain products, services, rates, and stock, and run the whole sales cycle from quote to invoice. [Verified](https://flowrunner.ai/integrations/verified "What does verified mean?") · 217 actions · API key · available [STEL Order website](https://stelorder.com/) · [Platform Documentation](https://app.stelorder.com/app/api/openapi.json) · Capability data verified 2026-08-24 1. A technician closes a work order at the customer's site 2. Agent reads the work delivery note, the parts consumed, and the serial numbers touched 3. The client's special prices and rate are resolved, so the job is billed at the price that client actually holds 4. Create Ordinary Invoice raises the invoice from the job with its item lines 5. The agent reconciles the invoice against the work order and the delivery note before proposing anything 6. The invoice and the filing it would trigger post to the billing owner 7. The billing owner approves the filing, because registering a document with the tax authority cannot be undone ## What This Integration Enables STEL Order is built for a business whose revenue starts at somebody else's site. That shape shows up all through its API. Assets are the equipment you maintain, incidents are what goes wrong with them, work estimates become work orders, work orders become work delivery notes, and only then does an ordinary invoice appear. Alongside that runs an ordinary sell side chain and a buy side chain, plus employees, calendars, serial numbers, stock movements, and a three layer pricing model where a client's special price beats an article's rate and an article's rate beats the list. FlowRunner agents work the full surface: parties and their addresses, the catalog and its pricing layers, the whole sales and purchase chains, work orders and incidents, expenses, assets, and the payment installments that actually mark a document paid. Two platform rules shape every flow built here rather than being per operation footnotes. Writes are one record at a time, because the vendor processes only the first element of an array and reports success anyway, so a ten record load is ten calls. And a deleted record vanishes from listings but stays readable by identifier and refuses any further modification, which is how a sync learns something was deleted rather than merely filtered out. The daily call budget is low enough that this matters commercially. A flow that re-reads whole tables on a schedule will exhaust it. A flow that filters on the last modification date and asks only for what changed will not, and the connector is built to make the second pattern the easy one. ### Without FlowRunner **The job and the bill live apart**: Work is scheduled in one system and invoiced in another, and the parts list is retyped **Pricing decided at the desk**: A discount someone remembers is applied by hand rather than read from the client's own rate **Filing done in a batch at month end**: Invoices are registered with the tax authority in a rush, long after the work happened ### With FlowRunner **The job produces the document**: The delivery note the technician left behind is what the invoice is built from **Pricing read from the record**: Special prices beat rates, rates beat list, and the agent resolves that order every time **Filing is a reviewed act**: Each registration is proposed with its evidence and approved by a named person before it leaves ## Use Case Scenarios ### The site visit that bills itself An incident is raised against an asset, and the agent creates a work order from it, resolves an employee whose role permits the job, and places an event on the technician's calendar. When the technician finishes, the work delivery note carries the parts consumed and the serial numbers touched. The agent then resolves pricing in the order the platform defines, checking the client's special price for each article before falling back to the rate, raises the ordinary invoice, and posts a summary to the dispatcher in [Slack](https://flowrunner.ai/integrations/slack). Nobody retypes the parts list, because the note the technician signed is the source of the lines. ### Receipts, not invoices, tell you what is paid Payment status in STEL Order does not live on the invoice. It lives in the receipts recorded against it, and the ordinary, purchase, and refund chains each have their own. On a schedule the agent walks the receipt listings for the period, pairs each against its document, and writes the aged position into [Google Sheets](https://flowrunner.ai/integrations/google-sheets) with the documents that are fully settled, partly settled, and untouched separated out. A payment captured in [Stripe](https://flowrunner.ai/integrations/stripe) becomes a receipt against the right invoice rather than a note somewhere near it. ### A prospect worked without touching the customer ledger Leads from a campaign or from [HubSpot](https://flowrunner.ai/integrations/hubspot) are created as potential clients, which are their own resource here rather than a flag on a client record. The agent maintains them, attaches contacts and addresses, and raises sales estimates against them. Only when an estimate is accepted does the flow propose promoting the prospect to a client, and that promotion is the point where a person checks the tax number, the payment terms, and the rate the new customer should sit on. Everything before it is reversible, which is exactly why the agent is allowed to do it unattended. ## Human-in-Loop Highlight Issue Invoice To Verifactu is not a status change inside STEL Order. Verifactu is the Spanish tax authority's invoice registration system, and issuing to it registers the document with the state. The connector's own description says the part that decides the design: it cannot be undone. Everything else in this API has a way back. A document can be updated, a deleted record still reads back, a rate can be corrected, an incident reopened. This one call leaves the software and files something with a government. So the agent builds the whole case and stops before the filing. It posts the invoice, the work order and delivery note it came from, the client's tax details, and the pricing path it took: "Invoice 2026/0418, 3,240 euros, raised from work order 8871. Client rate is Mantenimiento with two special prices applied. Tax number on the client record has not changed since the last filed invoice. File to Verifactu, or hold?" The billing owner answers. If the answer is hold, nothing has left the building and the invoice can still be corrected in place. If the answer is file, the correction path afterwards is a refund invoice, which is a permanent document of its own rather than an edit. The agent is quicker at assembling the case than any person. It has no business being the one who signs it. That is what a [human-in-the-loop](https://flowrunner.ai/concepts/human-in-the-loop) gate is for: not slowing the work down, but keeping the one irreversible act attached to a person. Agent processes routinely Detects exception requiring judgment Clear match Continues automatically Ambiguous Routes to human via preferred channel Human decides Agent resumes with decision ## Agent Capabilities 217 actions ### Parties 30 - **List Account Categories** Lists the account categories on a STEL Order account, with the vendor's own filters, sorting, and paging.

This is a legal filing rather than a status change inside STEL Order, and it cannot be undone.

The route reads like an update and it sends something, which is worth knowing before a flow calls it speculatively. Left without an address, the document's own account address is used. ## Frequently Asked Questions ### What can FlowRunner do with STEL Order?
